Much of the attention this week in tech was on the litany of quarterly earnings reports, but there's still news in the cryptocurrency and blockchain technology world to watch.

Catch up quick: An investigation into the industry's media pay-to-play; a judge dismissed an initial lawsuit against Coinbase over Bitcoin Cash listing; and the SEC's newest commissioner recently met with groups behind the Bitcoin exchange-traded fund (ETF) proposal.

• Why it matters: One unfortunate side of the boom in cryptocurrency and blockchain tech interest and activity is the rise of unethical trade press practices — namely some outlets charging fees to promote a project or company.

• Why it matters: Coinbase came under fire last year when the price of Bitcoin Cash spiked just hours before Coinbase announced its listing, leading to suspicions of insider trading.

Still, a judge has dismissed most of this lawsuit's claims without prejudice, meaning that the plaintiff can file a modified complaint that's clearer in making its case.
